| 摘 要： | 假定一个光学环腔内充满由N个二能级原子组成的介质,二能级原子同共振的腔场模发生作用,忽略其间变化。n光子同诸原子的相互作用能够被一个等效的、考虑了诸中间态累加作用的哈密顿量所表示,原子和场模的衰减由同库的相互作用来表示。那么,在电偶极和旋波近似下的全部哈密顿量为:

Flourescence problem in multi-photon optical bistability |
| |
| Abstract: | A quantum mechanics model used to describe a n-photon transition within an atomic system is presented, and a semiclassical approach is used to obtain Maxwell-Bloeh equations so as to describe the multi-photon optical bistability system. From these equations the conclusions can be easily derived as follows: under stationary conditions, the flourescence intensity of multi-photon optical bistability is propotional to N orN - 1/(2n-1)in the cooperative region and is propotional to N in the single atom region. |
